Comparing primary caregivers' reported injury data with routinely recorded injury data to assess predictors of childhood injury.

BACKGROUND: Linking self-reported data collected from longitudinal studies with administrative health records is timely and cost-effective, provides the opportunity to augment information contained in each and can offset some of the limitations of both data sources. The aim of this study was to compare maternal-reported child injury data with administrative injury records and assess the level of agreement. METHODS: A deterministic linkage was undertaken to link injury-related data from the Growing up in New Zealand (GUiNZ) study to routinely collected injury records from New Zealand's Accident Compensation Corporation (ACC) for preschool children. The analyses compared: (i) the characteristics of mothers with linked data vs. those without, (ii) injury incidences from maternal recall with those recorded in ACC injury claims, and (iii) the demographic characteristics of concordant and discordant injury reports, including the validity and reliability of injury records from both data sources. RESULTS: Of all mothers who responded to the injury questions in the GUiNZ study (n = 5836), more than 95% (n = 5637) agreed to have their child's record linked to routine administrative health records. The overall discordance in injury reports showed an increasing trend as children grew older (9% at 9 M to 29% at 54 M). The mothers of children with discordance between maternal injury reports and ACC records were more likely to be younger, of Pacific ethnicity, with lower educational attainment, and live in areas of high deprivation (p < 0.001). The level of agreement between maternal injury recall and ACC injury record decreased (κ = 0.83 to κ = 0.42) as the cohort moved through their preschool years. CONCLUSIONS: In general, the findings of this study identified that there was underreporting and discordance of the maternal injury recall, which varied by the demographic characteristics of mothers and their child's age. Therefore, linking the routinely gathered injury data with maternal self-report child injury data has the potential to augment longitudinal birth cohort study data to investigate risk or protective factors associated with childhood injury.

Slicing Through the Layers of Pediatric Unintentional Injury With the Swiss Cheese Model: A Topical Review.

Pediatric unintentional injury significantly burdens children, families, and society. Behavioral researchers have examined the problem for decades, identifying many risk factors and greatly enhancing knowledge of the injury antecedent process. Approaches using theories and models to guide inquiry into etiology and prevention are still needed. We offer an approach borrowed from the field of human factors to enhance understanding and prevention. We focus our exploration on an error modeling and accident investigation tool called the Swiss Cheese Model. We first introduce the basic elements of the model. Next, we apply error modeling concepts to example scenarios drawn from real unintentional incidents and discuss the implications for understanding etiology and prevention. Finally, potential future directions are discussed to illustrate paths for the advancement of injury etiology and prevention.

A rare case of anterior shoulder dislocation in 1-year- and 10-month-old toddler: case report and literature review.

We report our clinical experience of a 1 year and 10 month child with traumatic anterior shoulder dislocation who underwent non-operative reduction and Desault's bandage immobilization for 10 days. No associated fractures were found and after bandage removal, full ROM of the shoulder was immediately assessed. Further research is needed to unified guideline of treatment and the time of immobilization for this type of injury in pediatric population.

Hospitalised infants due to falls aged less 12 months in New South Wales from 2002 to 2013.

AIM: Falls are the most common injury mechanism of children <12 months in Australia. We aimed to determine the prevalence of hospital admission following a fall among New South Wales (NSW) infants and changes in admission rate over time. Secondary aims were to examine demographics, nature of injury and trends by age groups associated with developmental milestones and fall mechanism. METHODS: This was a retrospective, population-based study across NSW from 2002 to 2013 using the NSW Admitted Patient Data collection. Infants with recorded falls, external causes of morbidity and mortality and activity codes were assessed. Main outcome measures were absolute numbers, rates and proportions by year, age group, socio-demographics, fall mechanism, injury type, body region affected and admission outcome. RESULTS: A total of 4380 cases were identified. Numbers increased over years (342 in 2002 to 469 in 2013). Rate of admissions per 10 000 population were 40.37 in 2002 and 47.18 in 2013 (average increase 0.9% per year, P = 0.25). 76% resided in a major city, 23% resided in the least disadvantaged areas and 18% in the most disadvantaged. Falls from furniture and falls while being carried were most common. 85% suffered a head injury, 70% of which had a traumatic brain injury (TBI). There were seven deaths and one quarter of surviving infants were admitted for 2 or more days. CONCLUSIONS: Hospital admission following a fall is a long-standing problem with no improvement among infants in NSW, commonly leading to head injury and traumatic brain injury. Effective prevention interventions are needed.

Environmental change interventions to prevent unintentional home injuries among children in low- and middle-income countries: A systematic review and meta-analysis.

INTRODUCTION: Unintentional home injury is an important cause of death and disability among children, especially those living in low- and middle-income countries (LMICs). This systematic review aimed to synthesize evidence about the effectiveness of environmental interventions to prevent unintentional child injury and/or reduce injury hazards in the home in LMICs. METHODS: Seven electronic databases were searched for randomized controlled trials (RCTs) and controlled before and after (CBA) studies published up to 1 April 2018. Potentially eligible citations were screened by title and abstract and full texts of studies obtained. Synthesis was reported narratively, and where possible, meta-analysis was conducted. RESULTS: Four studies met the inclusion criteria: One CBA study reported changes in injury incidence, and three RCTs reported changes in frequency of home hazards. In one study, child resistant containers were found effective in reducing the incidence of paraffin ingestion by 47% during and by 50% postintervention. A meta-analysis of two trials found that home inspection, safety education and safety devices reduced postintervention mean scores for poisoning hazards [mean difference (MD) -0.77; 95% CI [-1.36, -0.19]] and burn-related unsafe practices (MD -0.37; 95% CI [-0.66, -0.09]) but not for falls or electrical and paraffin burn hazards. A single trial found that home inspection and safety education reduced the postintervention mean scores for fall hazards (MD -0.5; 95% CI [-0.66, -0.33]) but not for ingestion hazards. CONCLUSION: There is limited evidence that environmental change interventions reduce child injuries but evidence that they reduce some home hazards. More evidence is needed to determine if altering the physical home environment by removing potential hazards reduces injuries in LMICs.

Categorizing mothers' and fathers' conceptualizations of children's serious play-related injuries: "You won't grow a finger back".

BACKGROUND: There is inconsistency across child development and care literature in operationalizing serious play-related injury and also a lack of understanding of how mothers and fathers conceptualize serious play-related injury. The current study explores parents' perspectives of their 2- to 7-year-old children's serious play-related injuries in urban and rural areas of British Columbia and Québec, Canada, and provides an urban/rural and gender analysis of the results. METHODS: We conducted semistructured interviews with 41 mothers and 63 fathers from 57 families, a total of 104 participants, in urban and rural locations in British Columbia and Québec, Canada. We used a social constructionist approach to the research and reflexive thematic analysis to construct themes from participant responses and to inform the consequent categorizations of serious play-related injury. RESULTS: The results indicate four categories of parents' conceptualizations of serious play-related injury: (a) injury requiring medical intervention, (b) injury resulting in head trauma, (c) injury resulting in debilitation, and (d) broken bones. CONCLUSIONS: Child development and care advocates can use these categories to strengthen their communications with parents and to improve understanding of parents' conceptualizations of children's serious play-related injury.

Children's experience of physical harms and exposure to family violence from others' drinking in nine societies.

AIM: To study caregiver reports of children's experience of physical harm and exposure to family violence due to others' drinking in nine societies, assess the relationship of harm with household drinking pattern and evaluate whether gender and education of caregiver affect these relationships. METHOD: Using data on adult caregivers from the GENAHTO (Gender and Alcohol's Harm to Others) project, child alcohol-related injuries and exposure of children to alcohol-related violence (CAIV) rates are estimated by country and pooled using meta-analysis and stratified by gender of the caregiver. Households with and without heavy or harmful drinker(s) (HHD) are compared assessing the interaction of caregiver gender on the relationship between reporting HHD and CAIV, adjusting for caregiver education and age. Additionally, the relationship between caregiver education and CAIV is analysed with meta-regression. RESULTS: The prevalence of CAIV varied across societies, with an overall pooled mean of 4% reported by caregivers. HHD was a consistent correlate of CAIV in all countries. Men and women in the sample reported similar levels of CAIV overall, but the relationship between HHD and CAIV was greater for women than for men, especially if the HHD was the most harmful drinker. Education was not significantly associated with CAIV. CONCLUSION: One in 25 caregivers with children report physical or family violence harms to children because of others' drinking. The adjusted odds of harm are significantly greater (more than four-fold) in households with a heavy or harmful drinker, with men most likely to be defined as this drinker in the household.

How Do Mothers and Fathers Interact With Their Children After An Injury? Exploring the Role of Parental Acute Stress, Optimism, and Self-Efficacy.

OBJECTIVE: In the aftermath of a child injury, children and parents can jointly experience acute stress symptoms. Optimism and self-efficacy might buffer against post-traumatic stress disorder. Knowing that children are innately receptive to parent modeling, we were interested in exploring how parent acute stress, optimism, and self-efficacy might transpire in parent-child interactions and whether any differences existed between mothers and fathers. METHODS: We recruited 71 families of seriously injured children who were hospitalized for at least 24 hr. Parents completed self-report measures of acute stress, optimism, and self-efficacy. Children wore the Electronically Activated Recorder (EAR(2)); Mehl, M. R. [2017]. The electronically activated recorder (EAR): A method for the naturalistic observation of daily social behavior. Current Directions in Psychological Science, 26, 184-190) for a 2-day period postdischarge. The EAR recorded ambient sounds for 30 s every 5 min. The audio recordings were transcribed and coded. We derived a percentage of time spent with each parent (interaction time), and average ratings of the emotional tone of voice for each speaker. RESULTS: Overall, parental acute stress and self-efficacy were not associated with interaction time or emotional tone, and parents generally spent less time with older children. Compared to fathers, mothers spent significantly more time with their child, particularly for daughters, but mothers did not differ from fathers in emotional tone, acute stress, optimism, or self-efficacy. For mothers, optimism may be associated with greater interaction time and more positive emotional tone. CONCLUSIONS: The present study highlighted parent gender differences in time spent with children and enabled the inclusion of more fathers using a naturalistic observational tool.

Impact of the United States federal child tax credit on childhood injuries and behavior problems.

Children who grow up in poverty are at risk for various poor outcomes. Socioeconomic policies can shape the conditions in which families are raising children and may be effective at reducing financial strain and helping families obtain economic sufficiency, thereby reducing risk for poor health outcomes. This study used data from two surveys conducted in the US, the National Longitudinal Survey of Youth 1979 (NLSY79) and the NLSY79 Young Adult survey to determine whether the U.S. Federal Child Tax Credit (CTC), a socioeconomic policy that provides tax relief to low- and middle-income families to offset the costs of raising children, is associated with child well-being, as indicated by whether the child had injuries requiring medical attention and behavioral problems. Fixed-effects models, accounting for year and state of residence, detected a lower likelihood of injuries requiring medical attention (OR = 0.58, 95% CI [0.40, 0.86]) and significantly fewer behavior problems (b = -2.07, 95% CI [-4.06, -0.08]) among children with mothers eligible to receive a CTC, but only when it was partially refundable (i.e., mothers could receive a tax refund for a portion of the CTC that exceeds their tax liability) for families making as little as $3000 a year. Tax credits like the CTC have the potential to alleviate financial strain among families, and consequently, may have impacts on injury and behavior problems.

[The structure of the fatal mechanical injury in Russia (the analysis of the materials for the period from 2003 to 2017)]. / Struktura smertel'noi mekhanicheskoi travmy v Rossii (po materialam 2003-2017 gg.).

The objective of the present work was to analyze the results and efficiency of forensic medical expertises and investigations of the cases of the fatal mechanical injury in Russia carried out during the period from 2003 to 2017. The analysis included the data on the structure and personnel scheduling charts of the departments of forensic medical expertise of the corpses in the state-governed forensic medical expertise institutions. It was shown that the structure of the fatal mechanical injury differs in different regions of the country: some of them are characterized by the predominance of blunt traumas whereas road traffic injuries prevail in others. In addition, the analysis of the regional distribution of the gunshot injuries was carried out.

The Cellie Coping Kit for Children with Injury: Initial feasibility, acceptability, and outcomes.

PURPOSE: Physical and psychological challenges can arise from paediatric injury, which can impact child health outcomes. Evidence-based resources to promote recovery are limited. The low cost, portable Cellie Coping Kit for Children with Injury provides evidence-based strategies to help children manage injury-related challenges. This study aimed to describe intervention feasibility and explore initial outcomes (learning, quality of life [QOL], and trauma symptoms). METHODS: Three independent pilot studies were conducted. Child-parent dyads (n = 61) participated in the intervention; ~36% completed a 4-week follow-up assessment. RESULTS: Results suggested that the intervention was feasible (e.g., 95% of parents would recommend the intervention; >85% reported that it was easy to use). Over 70% of participants reported learning new skills. No statistically significant differences were detected for children's QOL or trauma symptoms preintervention to postintervention. CONCLUSION: Preliminary research suggests that the Cellie Coping Kit for Children with Injuries is a feasible, low-cost, preventive intervention, which may provide families with strategies to promote recovery from paediatric injury. Future research, including a randomized controlled trial, ought to further examine targeted long-term intervention outcomes.

Vitamin D and Fracture Risk in Early Childhood: A Case-Control Study.

The objective of this study was to evaluate the association of vitamin D intake and serum levels with fracture risk in children under 6 years of age. A case-control study was conducted in Toronto, Ontario, Canada. Cases were recruited from the fracture clinic at the Hospital for Sick Children, and matched controls were obtained from the TARGet Kids! primary-care research network. Controls were matched to cases on age, sex, height, and season. Fracture risk was estimated from conditional logistic regression, with adjustment for skin type, fracture history, waist circumference, outdoor free play, neighborhood income, soda consumption, and child's birth weight. A total of 206 cases were recruited during May 2009-April 2013 and matched to 343 controls. Serum 25-hydroxyvitamin D concentration (per 10-nmol/L increment: adjusted odds ratio (aOR) = 0.95, 95% confidence interval (CI): 0.88, 1.03) and intake of cow's milk (<2 cups/day vs. 2 cups/day: aOR = 0.95 (95% CI: 0.60, 1.52); >2 cups/day vs. 2 cups/day: aOR = 1.39 (95% CI: 0.85, 2.23)) were not significantly associated with reduced odds of fracture. A statistically significant association was observed between child use of vitamin D supplements and decreased odds of fracture (yes vs. no: aOR = 0.42, 95% CI: 0.25, 0.69). Vitamin D supplementation, but not serum 25-hydroxyvitamin D level or milk intake, was associated with reduced fracture risk among these healthy young children.

Breaking Out of Surveillance Silos: Integrative Geospatial Data Collection for Child Injury Risk and Active School Transport.

The preponderance of active school transport (AST) and child injury research has occurred independently, yet they are inherently related. This is particularly true in urban areas where the environmental context of AST may pose risks to safety. However, it can be difficult to make these connections due to the often segregated nature in which these veins of research operate. Spatial video presents a geospatial approach for simultaneous data collection related to both issues. This article reports on a multi-sector pilot project among researchers, a children's hospital, and a police department, using spatial video to map child AST behaviors; a geographic information system (GIS) is used to analyze these data in the environmental context of child pedestrian injury and community violence.

Characteristics of low-speed vehicle run-over events in children: an 11-year review.

OBJECTIVES: The purpose of this study was to investigate the characteristics associated with fatal and non-fatal low-speed vehicle run-over (LSVRO) events in relation to person, incident and injury characteristics, in order to identify appropriate points for intervention and injury prevention. METHODS: Data on all known LSVRO events in Queensland, Australia, over 11 calendar years (1999-2009) were extracted from five different databases representing the continuum of care (prehospital to fatality) and manually linked. Descriptive and multivariate analyses were used to analyse the sample characteristics in relation to demographics, health service usage, outcomes, incident characteristics, and injury characteristics. RESULTS: Of the 1641 LSVRO incidents, 98.4% (n=1615) were non-fatal, and 1.6% were fatal (n=26). Over half the children required admission to hospital (56%, n=921); mean length of stay was 3.4 days. Younger children aged 0-4 years were more frequently injured, and experienced more serious injuries with worse outcomes. Patterns of injury (injury type and severity), injury characteristics (eg, time of injury, vehicle type, driver of vehicle, incident location), and demographic characteristics (such as socioeconomic status, indigenous status, remoteness), varied according to age group. Almost half (45.6%; n=737) the events occurred outside major cities, and approximately 10% of events involved indigenous children. Parents were most commonly the vehicle drivers in fatal incidents. While larger vehicles such as four-wheel drives (4WD) were most frequently involved in LSVRO events resulting in fatalities, cars were most frequently involved in non-fatal events. CONCLUSIONS: This is the first study, to the authors' knowledge, to analyse the characteristics of fatal and non-fatal LSVRO events in children aged 0-15 years on a state-wide basis. Characteristics of LSVRO events varied with age, thus age-specific interventions are required. Children living outside major cities, and indigenous children, were over-represented in these data. Further research is required to identify the burden of injury in these groups.

Effect of educating mothers on injury prevention among children aged <5 years using the Health Belief Model: a randomized controlled trial.

OBJECTIVES: To assess the effect of the Health Belief Model (HBM) on the education of mothers for promoting safety and preventing injury among children aged <5 years. STUDY DESIGN: Randomized controlled trial. METHODS: This study was conducted in Hamadan City, West Iran in 2012. One hundred and twenty mothers participated in this study, divided into intervention and control groups (60 mothers in each group). The intervention group participated in an educational programme consisting of four 1-hour sessions twice per week. The education programme was based on the HBM. The participants of both groups were evaluated before the intervention and two months after the intervention using a questionnaire. The validity and reliability of the questionnaire were tested with a pilot study. The questionnaire consisted of three parts: demographic characteristics; knowledge, practices and HBM constructs (perceived sensitivity, perceived severity, perceived benefits, perceived barriers, cues to action and self-efficacy); and history of recent injuries to the child. Student's t-test was used to compare the mean differences, and P < 0.05 was considered to indicate significance. RESULTS: None of the 120 participants dropped out of the study. The mean differences in knowledge, perceived susceptibility, perceived severity, perceived benefits, perceived barriers, cues to action, self-efficacy and practices after the intervention, between the two groups, were 3.98, 3.57, 3.97, 1.57, -7.08, 0.82, 2.95 and 2.47, respectively. All differences were statistically significant (P = 0.001). CONCLUSIONS: Educational programmes based on the HBM can be used as an effective approach in planning and developing preventive programmes for injury prevention and safety promotion in children aged <5 years.

The effects of postural support padding modifications to child restraints for children with disability on crash protection.

OBJECTIVE: Many children with physical disabilities need additional postural support when sitting and supplementary padding is used on standards approved child restraints to achieve this when traveling in a motor vehicle. However, the effect of this padding on crash protection for a child is unknown. This study aimed to investigate the effect of additional padding for postural support on crash protection for child occupants in forward facing child restraints. METHODS: Forty frontal sled tests at 49 km/h were conducted to compare Q1 anthropometric test device (ATD) responses in a forward-facing restraint, with and without additional padding in locations to increase recline of the restraint, and/or support the head, trunk and pelvis. Three padding materials were tested: cloth toweling, soft foam, and expanded polystyrene (EPS). The influence of padding on head excursion, peak 3 ms head acceleration, HIC15, peak 3 ms chest acceleration and chest deflection were analyzed. RESULTS: The influence of padding varied depending on the location of use. Padding used under the restraint to increase the recline angle increased head injury metrics. Toweling in multiple locations which included behind the head increased head excursion and chest injury metrics. There was minimal effect on injury risk measures with additional padding to support the sides of the head or the pelvis position. Rigid EPS foam, as recommended in Australian standards and guidelines, had minimal effect on injury metrics when used inside the restraint, as did tightly rolled or folded toweling secured to the restraint at single locations around the body of the child. CONCLUSIONS: This study does not support the use of postural support padding to increase recline of a forward-facing restraint or padding behind the head. Recommendations in published standards and guidelines to not use foam that is spongy, soft or easily compressed, with preference for secured firm foam or short-term use of tightly rolled or folded toweling under the child restraint cover is supported. This study also highlights the importance of considering the whole context of child occupant protection when using additional padding, particularly the change in the child's seated position when adding padding in relation to the standard safety features of the restraint.

History of airbag safety benefits and risks.

OBJECTIVE: The history of airbags was reviewed for benefits and risks as they became a supplement to lap-shoulder belts. Sled and crash tests were evaluated and field data was analyzed for airbag effectiveness. Field data on airbag deaths and studies on mechanisms of deployment injury were analyzed. The history was reviewed as airbags evolved from the early 1970s to today. METHODS: Airbag benefits were determined from NHTSA crash tests with unbelted and belted dummies in 40, 48, and 56 km/h (25, 30, and 35 mph) frontal impacts with and without airbags. The literature was reviewed for testing of passive restraints with and without airbags. Recent NCAP tests were compared with earlier tests to determine the change in occupant responses with seatbelts and supplemental airbags in modern vehicles. 1994-2015 NASS-CDS field data was analyzed for MAIS 4 + F injury. Risks were compared for belted and unbelted occupants in frontal impacts by delta V. Airbag risks were identified from field deployments and research. The 1973-76 GM fleet had two deaths due to the occupant being out-of-position (OOP). The mechanisms of injury were determined. From 1989-2003, NHTSA investigated 93 driver, 184 child passenger, and 13 adult passenger airbag deaths. The data was reviewed for injury mechanisms. Second generation airbags essentially eliminated OOP airbag deaths. More recently, three suppliers were linked to airbag rupture deaths. The circumstances for ruptures were reviewed. RESULTS: The risk for serious head injury was 5.495% in drivers and 4.435% passengers in 40-48 km/h (25-30 mph) frontal crash tests without belts or airbags. It was 80.5% lower at 1.073% in drivers and 82.0% at 0.797% in passengers with belts and airbags in 35 mph NCAP crash tests of 2012-20 MY vehicles. NASS-CDS field data showed a 15.45% risk for severe injury (MAIS 4 + F) to unbelted occupants and 4.68% with belted occupants in 30-35 mph frontal crash delta V with airbags, as deployed. The reduction in risk was 69.7% with belt use and airbags deploying in 96.1% of crashes. There were benefits over the range of delta V. Two airbag deaths were studied from the 1970s GM fleet of airbags. The unbelted driver death was caused by punchout force with the airbag cover blocked by the occupant and membrane forces as the airbag wrapped around the head, neck or chest with the occupant close to the inflating airbag. The unbelted child death was from airbag inflation forces from pre-impact braking causing the child to slide forward into the deploying airbag. Research showed that unrestrained children may have 13 different positions near the passenger airbag at deployment. NHTSA investigation of first generation airbag deaths found most driver deaths were females (75.3%) sitting forward on the seat track, close to the driver airbag. Seatbelt use was only 30%. Most child deaths (138, 75.4%) involved no or improper use of the lap-shoulder belts. Of these, 115 deaths involved pre-impact braking. Only 37 (20.2%) children were in child seats with 29 in rear-facing and 8 in forward-facing child seats. Eight child deaths (4.4%) occurred with lap-shoulder belt use. Airbag designs changed. More recently, Takata airbags were related to at least 24 deaths by airbag rupture prompting a recall; the successor company Joyson had an airbag recall. ARC airbags have experienced a chunk of the inflator propelled into the driver during deployment with several deaths leading to a recall. CONCLUSIONS: Airbags are effective in preventing death and injury in crashes. They provide the greatest protection in combination with seatbelt use. NHTSA estimated airbags saved 28,244 lives through 1-1-09 while causing at least 320 deployment deaths, which has prompted improved designs, testing, and recalls.

Childhood burn injury in the ger districts of Ulaanbaatar, Mongolia: an analysis of parent narratives.

Childhood burns pose a significant public health concern, particularly in low- and middle-income nations, where the burden is pronounced. Mongolia stands out for its elevated rates of burn-related child mortality, especially among 1 to 5-year-olds. Despite this, there is a lack of research on the current status of childhood burns in Ulaanbaatar. This study utilized Cognitive Edge's Sensemaker® to collect micronarratives from parents in the ger districts of Ulaanbaatar, aiming to understand the present context of childhood burn injuries. Thematic analysis revealed four key themes, including features in home and outdoor environments, lack of safety measures, and limitations in supervision. The findings emphasize the need for a comprehensive approach to burn injury prevention tailored to the Mongolian context. Implementing suitable safety measures in ger districts based on these results could be instrumental. Additionally, extending this approach to other low- and middle-income countries warrants further investigation for effective preventive measures.

Exploring the Potential of a Behavior Theory-Informed Digital Intervention for Infant Fall Prevention: Mixed Methods Longitudinal Study.

BACKGROUND: Falls are the most common hospitalized injury mechanism in children aged ≤1 years, and currently, there are no targeted prevention interventions. The prevention of falls in children of this age requires changes in the behavior of their caregivers, and theoretically informed digital behavior change interventions (DBCIs) may provide a unique mechanism for achieving effective intervention. However, user acceptance and the ability of DBCIs to effect the required changes in behavior are critical to their likelihood of success. OBJECTIVE: This study aims to evaluate a behavior theory-informed digital intervention developed following a user-centered approach for user experience, the potential for this intervention to prevent infant falls, and its impact on behavioral drivers underpinning fall risk in young children. METHODS: Parents of infants aged <1 year were recruited and asked to use the intervention for 3 months. A pre-post longitudinal design was used to examine the change in the potential to reduce the risk of falls after a 3-month exposure to the intervention. Postintervention data on behavioral drivers for fall prevention, user acceptability, and engagement with the app were also collected. Interviews were conducted to explore user experiences and identify areas for further improvement of the intervention. RESULTS: A total of 62 parents participated in the study. A statistically significant effect on the potential to reduce falls was observed after the intervention. This effect was higher for new parents. Parents agreed that the intervention targeted most of the target behavior drivers. The impact of behavior drivers and intervention on the potential for fall prevention had a positive correlation. The intervention demonstrated good levels of acceptability. Feedback from participants was mostly positive, and the primary area identified for further improvement was widening the scope of the intervention. CONCLUSIONS: This study demonstrated the promise of a newly developed digital intervention to reduce the risk of infant falls, particularly among new parents. It also showed a positive influence of the DBCI on the drivers of parental behaviors that are important for fall reduction among infants. The acceptability of the app was high, and important insights were gained from users about how to further improve the app.

Preventing posttraumatic stress following pediatric injury: a randomized controlled trial of a web-based psycho-educational intervention for parents.

OBJECTIVE: The study objective is to evaluate the feasibility and efficacy of a web-based intervention for parents (AfterTheInjury.org [ATI]) in promoting emotional recovery following pediatric injury. METHODS: 100 children with injuries requiring medical attention and their parents were randomly assigned to the intervention or usual care. Efficacy outcomes included parent knowledge and child and parent posttraumatic stress symptoms (PTSS). RESULTS: All parents in the intervention group completed the intervention (directed use of ATI) in the hospital. 56% reported using ATI online post-discharge, and 100% of these parents found it helpful. Parent knowledge increased immediately post-intervention, but there was no significant intervention impact on parent knowledge or PTSS at a 6-week follow-up. Relationships between knowledge and PTSS were identified. CONCLUSIONS: Brief web-based interventions introduced during child hospitalization are a feasible strategy to reach many parents following pediatric injury. Preventing psychological symptoms may require more than parental education alone.
